Mandatory service refers to a system where individuals are required by law to serve in a specific capacity, often in the military or community service. This obligation can vary in duration and is typically implemented during times of national need or to promote civic responsibility. Countries like Israel and South Korea have established mandatory military service for eligible citizens. In addition to military duties, mandatory service can also include programs focused on community development, education, or disaster relief. Such initiatives aim to foster a sense of duty and engagement among citizens, encouraging them to contribute positively to society while gaining valuable skills and experiences.
